My drain plug is leaking but I think I forgot to put thread tape on it when I rebuilt the trans. Regardless the 3/8 socket insert is damaged due to me having hell getting it out. I have been told it is 1/2 npt. Do they seel these at local auto parts like AZ or Oreilly's? Can you get one from some place like Home Depot? Otherwise where is the best place to order one? I have searched on ebay but I can't get confirmation they are for the t-5 world class. I have seen several for the t56 but not sure if they will work.
